This invention relates to an improvement in a bushing structure and has for its primary object the purpose of providing a bushing n a'metallic barrel head in a manner wherein the bushing cannot be turned by the. plug thereofduring tightening or loosening of the Another object of the invention is in providing an inexpensive bushing structure in a metallic barrel head and which is exceedingly simple in the making and mounting thereof. Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being 13 had in the accompanying drawings, exempli-.

Referring by numerals to the accompany- "lng drawings, 1 designates a fragmentary portion of a metallic barrelhead having the ung hole or opening 2 formed therein and- The bushing 6 to be inserted in-the bung hole2 is comprised of an annular flange 7 having concentrically formed depending neck 8, said neck being of a diameter so as to ,4 of which there area =12 fand are bended over respective "edges iof l said recesses} The ext is inserted in'the hole o-Lf'the-Qbarrelflthenoutwardly pressed over h l during the formation of the bun hole it is 4o requisite that the material of the arrel head be snugly fitted in the bung hole, The neck of the'bushing 6 has an interiorly threaded portion 9, said neck beneath said threaded portion having a portion 10 which is reduced 1n thickness annularly there-around and extending from the lower edge 11 ot said bushing and within the portion 10 is a plurality of recesses 12.

In securing the bushing 6 in the bung hole of the barrel head a igasket 13' is'first mount- I ed over the neck 8 o the bushing and seated against the flange 7 then the neck 8 is inserted in the bung hole 2 of the bung ,hole neck 3 of the barrel head as shown in Fig. 4. In this seated'position of the bushing it will be noted from an inspection of Fig. 4 that a.

partof the portion 10 of the neck8 of said i bushing is depended beneath the edge 5of 4 the bung hole neck 3 and the recess 12 of the bushing neck 8 is positioned in alinement i with. the. tongue 4 of the neck 3. The tongues turned inwardly through.irespectivegrecesses thefbushingsin .the bfu i, ur g f t on 3': 4-1 m ceases-12: of the bushing 6, wil p e of he turning of the closure or bung, not shown when the bung is mounted ".inthe bushing. 7

From the aforesaid description of this improved bushing structure in connection with a metallic barrel, it is obviousithat a simple, inexpensive and eflicient bushing structure is provided.

-' It is to be. noted that several figures of rplurality-are 'ach barrel head as shown by dotted lines 16 in Fig, 1.

What I claim is f 1. A container havin a bung hole with 11 depending neck formef in one of itsswalls, a pai r of tongues depending from the lower end of said neck, a bushing mounted in said neck having a pair of recesses, each of said tongues adapted to be engaged in a respective recess of said bushing, said blushing h'av ing a portion of its lower extremity bent over the lower edge of said neck. W

2; A. barrel having a bung hole formedin one of its walls, a depending neck formed of the material surrounding the bung hole having portions projecting from its lower end, an interiorly threaded bushing mounted in said neck having a relatively thin lower extremity bent over the lower edge of .said neck, said lower extremity of said bushing havingrecesses therein for cooperation with the projections of said neck for preventing said bushing being turned in said neck.

3. A metallic container having a hung hole formed ,in one of its walls with a surrounding depending neck and having portions projecting from the lower end of the neck, an

interiorly threaded bushing mounted in said neck having a relatively thin lower extremity with recesses therein, each of said projecting portions of said bung hole neck adapted to be engaged in a respective recess of said bushing and bent inwardly and over the lower extremity of the bushing neck beneath the threads thereof, the portions of the lower extremity of said bushing between the recesses thereof being bent outwardl over the lower edge of said bung hole nec thereof.

1. A container having a hung hole with a depending neck formed in one of its walls,

a plurality of tongues extending from the lower end of said neck, a bushing mounted interiorly of said neck having a plurality of recesses, each of said tongues adapted to be engaged in a respective recess of said bushing, the lower extending end of said bushing between the recesses being bent over the lower edge of said neck between the tongues LOUIS- B.
